The pair were spotted with Niall’s One Direction bandmate Lous Tomlinson, and were even rumoured to have run into DJ Calvin Harris on the night out.
Eagle-eyed Directioners spotted the pair laughing together, surrounded by alcohol, after Ed’s performance – and appeared ready to do a line of shots together.
The pair were rumoured to have fallen out after Niall apparently got with Ed’s then-girlfriend Ellie Goulding.
The guitar strummer penned Don’t about an old girlfriend cheating on him with a pal – heavily rumoured to have been written about his One Direction band member friend Niall and Ellie.
However the past is the past, and when asked previously if he is a forgiving person, Ed told The Sun newspaper: “I guess. I got over the anger the moment I wrote the song.
“That’s the end of it. I’m grateful I could get a song out of it, to be honest.
“I don’t feel it’s about anyone any more, I’m not attached to that. The moment you attach someone to a song it becomes more difficult to sing every night.”
Niall and Ed were pictured sharing a friendly hug in Las Vegas last year, proving that if there ever was a feud, it’s certainly now in the past.
